Giant hydronephrosis secondary to ureteropelvic junction obstruction, a rare occurrence, case report

Giant hydronephrosis (GH) is very rare in adults. We report a case of a 46-year-old man who presented with progressively increasing abdominal swelling. A contrast-enhanced CT scan of the abdomen and pelvis was used for the diagnosis. Left side open nephrectomy was performed and 22 L fluid was evacuated. UPJ obstruction was noted intraoperatively. No recurrence of abdominal swelling was noted on follow up examination.
